DESCRIPTION
DESCRIPTION
Polaris engagement ring in 18K gold with central diamond
The Polaris ring is born as a symbol of connection, of those bonds that mark a before and after in our lives. Crafted in 18K gold, its central brilliant cut diamond captures the light and transforms it into hundreds of sparkling reflections.
Its cut, in a round shape with approximately 58 facets, is designed to maximise light return, inspired by the surface of the Moon. This gives it a unique character that sets it apart.
At San Saru, we believe in stories built step by step, in moments that stay forever. That is why this ring is not just a piece of jewellery, it is a promise.

Size guide
The best way to find your ring size is to follow the steps in this guide. Choose the method that works best for you and you will know your exact size in just a couple of minutes.
Ring size guide
We offer two types of rings: adjustable rings and fixed-size rings. If yours has a fixed size, here are three different ways to find it so you can choose the method that feels easiest.
Almost all our rings are available in sizes 8 to 20, and some models are available up to size 24. Please note that thicker rings usually fit a little more snugly than thinner ones.
If you prefer not to depend on a specific size, we also offer adjustable rings. They adapt to different finger sizes, so you do not need to know your size in advance. Each model covers a different size range, which is listed in its product description.
We also offer midi rings and toe rings, designed to be worn on your toes, halfway up your finger or even as a regular ring, depending on your size. These models are available in size S (equivalent to size 4) and M (equivalent to size 6).
Bracelet size guide
To help you understand the measurements of our bracelets, we have created a guide that you can print and use directly on your wrist.
If you have any questions, contact us at info@sansarushop.com.
Here are four different ways to find your ring size. Choose whichever method feels most comfortable, but if you are between two sizes, always choose the larger one.
Option 1. Using your phone camera
Measure your finger with your phone in under two minutes, without a printer or another ring for reference.
- Open the product page of the ring you like and select “Find my size”, just below the size selector.
- If you are using a computer, scan the QR code with your phone camera. If you are already on your phone, select “Find my size” and continue there.
- Allow camera access and follow the on-screen instructions to measure the finger on which you will wear the ring.
- When you finish, you will see your size and can return to the ring page with that size already selected.
Bear in mind that sizing can vary from one finger to another and between your right and left hands. Always measure the exact finger on which you plan to wear the ring. A thicker ring will usually fit a little more snugly than a thin one.
You can also measure your size directly from here now:
Option 2. Finger sizer
- Print this size guide on an A4 page and make sure the print scale is set to 100%.
- To check that it printed correctly, measure the reference line with a ruler and make sure it is 10 cm long.
- Cut out the sizer along the solid outline marked with the scissors.
- Carefully cut along the central dotted line using a craft knife or scissors.
- Assemble the sizer by rolling it with the printed side facing outwards and threading it through the slit.
- Place the sizer around the finger you want to measure and gently pull the end until it no longer slides, without making it feel tight.
- The sizer will show your size. If it falls between two sizes, always choose the larger one.
Option 3. Ring sizer
- As with the previous option, print this page with your printer scale set to 100%.
- To check that the printed measurement is correct, measure the indicated scale with a ruler and make sure it is exactly 5 cm long.
- Take a ring that already fits you the way you would like your San Saru ring to fit and place it over the circles.
- The circle should fit neatly inside the ring, without the ring covering the line or leaving a gap. You have now found your size.
Option 4. Without a printer
- Take a ring that already fits you the way you would like your San Saru ring to fit, along with a ruler.
- Measure the ring’s inner diameter straight across the centre.
- Compare that measurement with the conversion table below.
